Cloudflare blocking domain

Problem statement

We ran into an error when using a self-managed custom domain from Cloudflare:

You’ve requested a page on a website ( that is on the Cloudflare network. An unknown error occurred while rendering the page.


If the Custom Domain is Auth0-managed, reach out to Auth0 support.

Otherwise, if it’s self-managed, reach out to Cloudflare via your account to ensure no blocks are applied.
